BreepinG Notres.—This species, unlike the herring gull and the 
ring-bill, breeds in communities in marshes. Hundreds of nests 
were found June 13th, 1894, in a marshy lake about three miles 
southeast of Crane lake; incubation was far advanced. The nests 
were very bulky, made of reeds placed on the marsh, and floating 
in about two and a half feet of water. Eggs in each case, three. 
(Spreadborough.) Breeds abundantly in the marshes at the south 
end of Lake Manitoba. (Razne.) 
60. Bonaparte Gull. 
Larus philadelthia (ORD) GRaAy. 1863. 
Frequent on the Atlantic coast as far north as Newfoundland. 
Apparently quite common in the Gulf of St. Lawrence and not 
rare in Hudson bay. A common spring and fall resident in 
Ontario. 
This species is found from Manitoba to the Pacific and a few 
doubtless breed in the prairie region, but its range is generally 
north of that of Larus franklinitz. No doubt the two are often con- 
founded. Its breeding range is in the wooded country ex ending 
from the Hudson bay westward to the marshes of the Yukon 
where Dall found it breeding. It is rare on the coast of Alaska 
but common along the British Columbian coast and very common 
on all the lakes of the interior of that province. 
BREEDING Notes.—Thirty-seven nests were taken between June 
10th and July roth, in the wooded country in the vicinity of Fort 
Anderson and on the lower Anderson river. The nests were all 
built on trees, from four to twenty feet from the ground, and with 
one exception were made of small sticks and twigs lined with hay 
and mosses. (Ma /farlane.) 
On June 11th, 1891, I found a few pairs of this little gull breed- 
_ ing in company with herring gulls, avocets and common terns on 
an island in a small lake north of Rush lake, Sask. (See ‘“ Bird- 
nesting in Northwest Canada,” page 57.) One specimen of the 
bird was procured to prove identity. This bird usually makes its 
nest in bushes and willows near the water, but in localities where 
there are no bushes it makes its nest on the ground like the other 
gulls. The eggs are similar to those of the Franklin gull, but are 
smaller in size. (Razne.)
